FB SKD misuses the FBNativeAdsManager SDK (-[UIApplication delegate] must be used from main thread only)

Bug Report

The react-native-fbads library misuses the official FBNativeAdsManager.h API by calling a function from a background thread that expects to be called from the UI thread:

Note: It might also be that the FBNativeAdsManager.h library should dispatch to the UI thread for those invokations instead, but I don't know how to report bugs for that library!

Note; I found a sample usage of the loadAds function, and they also call it from the UI thread. Since the code of the facebook ads SDK is private I don't know if they're dispatching network requests to the background thread, but I can assume they do. I replaced the problematic line in the screenshot with the following:

    dispatch_async(dispatch_get_main_queue(), ^{
        [adsManager loadAds];
    });

and everything seems like it's working fine. I'd suggest you try if this has any side-effects, and if not also update this package using this.
